E. WEBB, F WATERTOWN, NEW YORK WINDOW 7 CONSTRUCTION Application filed February 24, 1927. Serial No. 170,530.

The invention relates to windows having sliding sash members and has for its object the provision of means by which the sash frames are detachably secured to sliding bars of the window frame to enable ready removal of the sash members from the window frame for cleaning or repair.

A further object of the invention is the provision of a window construction including a window frame having grooves in its stiles in which are slidably mounted bars connected with the counterweights or other means for holding the sash in adjusted position, and providing the sash members with grooves in their stiles to receive the bars, and means carried by the sash members to secure the members to the bars for movement therewith, the construction admitting of attachment of the sash members from the bars for removal of the sash members from the frame for cleaning or repair. e

The invention will be described in detail hereinafter and will be found illustrated in,

Figure 2 is a vertical sectional view on a.v

' plane indicated by the line 22of Figure 1,

and

Figures 3 and 4'are sectional details on an enlarged scaleon planes indicated by the lines 38, and 4-4 of Figure 1.

In the drawings similar reference characters will be used to designate corresponding parts throughout. the several views.

' Thewindow frame is indicated at 1 and has spaced strips 2 secured to its stiles 3. providing grooves 4 therebetween in which are slidably mounted bars 5 having recesses 6 0 in their upper ends in which are secured sash cords 7 carrying counterweights 8 and trained over pulleys 9, or any other conventional construction of means for countering the weight of the sash may be employed, such other means not being shown as the application thereof is obvious and is considered to be unnecessary to specifically show and describe.

The window sash 10 is provided with grooves 11 in its stiles to receive the bars 5, 5, and 12 designates pins slidably engaging openings 13 in the sash stiles that engage in recesses 14 of the bars 5 to hold the sash for movement with the bars. The upper ends of the stiles of the window sash 10 are provided with openings 15'to permit removal of the sash 10 from the window frame for repair or cleaning, and the upper ends of the bars 5 are provided with offsets 16 that engage in and fill the openings 15 when the sash 10 is secured to the bars.

The advantages of the invention will be apparent as by the construction as shown and described it will be understood that the sash members of a window may be readily removed and replaced relatively to the frame, as the sash member 10 may be released from the sliding bars 5 by sliding the sash and attached bars 5'to the top of the frame. The pins 12 will then be withdrawn from engagement with recesses 14 and the sash slid downwardly on the bars 5 to the lower part of the frame when it will be readily removable from the window frame, the openings 15 providing for removing the lower ends of bars 5 from the grooves 11 when the sash is lowered relatively to the bars 5. When the sash is in the position secured to the bars 5 as indicated at the left side of the frame shown in Figure 1 the sash may be raised or lowered in the frame and will be held'in adjusted position by means of the counterweights 8 or other means for countering the weight of the sash member. Furthermore the oifsets 16 provide bearings for the bars 5 to prevent binding between the sash 10 and the strips 2.

'What is claimed is A, Window construction, comprising a frame having grooves in its stiles, bars slidably mounted in said grooves, a sash member having grooves in its side members to receive said bars and openings in the side members communicating with the grooves, means to secure the sash member to the bars, and offsets on the bars toseat in the openings in the sash 10o member, said offsets providing bearings for the bars slidably engaging the frame on the sides of the grooves therein to prevent the sash member from binding in the frame durmg sliding movement thereof.

In testimony whereof I aflix my signature.
